Abstract
A lockout prevention system for safety switches. The system may be universal, in that it may be installed on various different brands and styles of industrial safety switch gear boxes. The system blocks a locking aperture when a lever arm is in a “non-off position” (e.g. displaced away from the “off” position). This prevents users from accidentally locking a padlock in the locking aperture while the switch is in an “on position”. The system still allows a user to lock the lever arm in the “off position”. The device may be universally mounted to switch boxes using two or more bolts. Further, the system is height-adjustable.
Claims20
A lockout prevention system for safety switches configured to be installed on various different brands and styles of industrial safety switch gear boxes, the system comprising:
- one or more panels that are configured to rotate due to the rotation of a switch handle of a switch gear box such that when the switch handle is in a non-off position an OEM locking aperture of the switch gear box is blocked from receiving a locking device in the non-off position, preventing users from accidentally locking a padlock in the locking aperture in the non-off position.
A lockout prevention system for safety switches configured to be installed on various different brands and styles of industrial safety switch gear boxes, the system comprising:
- one or more panels that are configured to rotate due to the rotation of a switch handle of a switch gear box such that when the switch handle is in a non-off position an OEM locking aperture of the switch gear box is blocked from receiving a locking device in the non-off position, preventing users from accidentally locking a padlock in the locking aperture in the non-off position;
- and
- wherein the system includes two moving panels and one fixed panel.
A lockout prevention system for safety switches configured to be installed on various different brands and styles of industrial safety switch gear boxes, the system comprising:
- one or more panels that are configured to rotate due to the rotation of a switch handle of a switch gear box such that when the switch handle is in a non-off position an OEM locking aperture of the switch gear box is blocked from receiving a locking device in the non-off position, preventing users from accidentally locking a padlock in the locking aperture in the non-off position;
- wherein a first panel is disposed closest to a side of a safety switch;
- wherein a second panel is disposed in between the first panel and a third panel;
- wherein the first panel is configured to attach the system to the switch box via one or more fasteners;
- and
- wherein the third panel is configured to rotate directly with respect to operation of the handle.
